Photo Essay on the impacts of blasting and tunneling for hydropower projects in Chamba district in Himachal Pradesh – 1

Tunneling for hydropower project using the blasting technique can have massive impacts. It has a series of direct and indirect impacts which have already been documented. Among the most serious impacts is drying up of the natural drinking water springs and the reduction in sub-soil moisture. This directly impacts the drinking water availability for the local villagers as well as agriculture and horticultural productivity, which is critically dependent upon the presence of sub-soil moisture. Blasting for tunnels and other underground components of hydroelectricity projects creates vibrations that have resulted in cracks in houses situated near these components.

Importance of impacts of tunneling and blasting becomes very important since all run of the river (ROR) projects involve tunneling and blasting. Proponents claim that ROR hydropower projects are environment friendly, but most people do not know that the tunneling and blasting adds an additional dimension to the impacts due to ROR hydropower projects and these can be very serious. Most environmental and social impact assessments or cumulative impact assessments do not even assess these impacts. Many times the proponent get away claiming that the impacts are not due to the projects, when in reality all evidence shows that these are very much caused by the tunneling and blasting being done as part of the construction of these projects.

This photo essay documents the impacts of tunneling and blasting for hydropower projects mainly in Chamba (part II of photo essay does the same for projects in Kinnaur district) of Himachal Pradesh. In Chamba, the photo essay includes such impacts of Chamera III, Chanju, Ginni, A.T. hydropower projects.[2] It is noteworthy that impacts are not only limited to large hydropower projects, but also to what is defined as small hydropower projects (projects below 25 MW installed capacity). This should also help puncture the misconceived notion that small hydropower projects are environmental benign and they do not need environmental and social impact assessment, public consultations, appraisal, monitoring or compliance.

These photo essays are indicative of the kind of impacts tunneling and blasting can have in the process of building hydropower projects in the Himalayas. What they indicate is relevant not only for Himachal Pradesh, but entire Himalayas and all projects that involve such tunneling and blasting. We hope these photo essays open the eyes of state governments, Union Ministry of Environment, Forests & Climate Change, Union Ministry of Power, Union Ministry of Water Resources, Central Electricity Authority, state environment departments, hydropower developers, EIA consultants, chairman and members of Expert Appraisal Committee on River Valley Projects, media, judiciary, civil society and all others concerned.

In April 2012 there was a massive leakage in the 16km HRT of the 231 MW, Chamera III project just above the Mokhar village in Chamba district leading to severe threat to the village downhill so much so that the 40 families residing there had to be evacuated. This picture is of the Adit 6 of the tunnel. The leakage occurred during testing of the generating units.Leakages in the surge shaft of the 231 MW Chamera III tunnel just above the Mokhar village in ChambaVidya Devi’s house in Mokhar was completely damaged by the landslide caused due to the seepage from the surge shaft in April 2012Shri Jagdish Sharma standing in front of the debris of his leftover house after the leakage tragedyThe pastures of the village buried under the landslide caused by the seepages in Mokhar villageDamages caused by the leakage in the HRT to houses in Mokhar villageDamages caused by the leakage in the HRT to houses in Mokhar villageDamages caused by the leakage in the HRT to houses in Mokhar villageDamages caused by the leakage in the HRT to houses in Mokhar village

Watermill rendered dysfunctional due to landslide cause by construction work for the 5MW Ginni Project in Tarela village in Chamba. The Project also diverted the water that was being used by the village for the watermill. Almost 15-20 watermills in this village have dried up due to the project’s construction activitiesThe location of the landslide which dried up the watermill

Landslide due to the construction activities and then subsequent destruction of the penstock of the Ginni project further led to soil erosion. The village above the slides, Junas has 20 houses and now stand threatened

Due to construction of hydroprojects it may affected land environment climate and destroyed many watermill and also drying the underground water.most of the company or contractor not following hse policey .whenever a new project is start firstly give jobs for the landlooser or particular villagers who may directly affected by the construction work and seconly prior to job for who belonging the counsituency
